I don't know what to call it, but my single rotor is running on something the supplier is calling fuel injection. In reality it is a somewhat advanced Ellison carburetor. It operates without electricity, has full mixture control and a primer, which can be used for over riding vapor lock in the fuel lines. So far, I have around 50hrs run time on the ground on two different engines including 1hr in the air. It may be supplied from a fuel pump or gravity feed. The engine never have staring problems. The air time was 3 flights, with the third one ending in a dead stick landing because of engine overheating.

The 12A based single rotor flows around 10 GPH of gas at 6300RPM WOT.

I have not seen a carburetor, during the single rotor development, performing comparably.

Hope to be in the air again soon.

FWIW

Hi Guys,
Something that might be of interest is that the ORIGINAL Powersport engines were setup with Airflow performance fuel injection. It required a fuel pump (which could be mechanically driven) but used a electric fuel pump. Works very well. Not quite as accurate as the modern electronic injection, but can be run without a battery.

Hi, the info from B&S for the EFI system is a bit sketchy at the moment. It is an open-loop system from Kokusan and completely different to the Delphi EFI on the 810 and the big block engines:

=C2=A0

Vanguard has also developed a horizontal shaft small-block (627 cc) engine, with an initial application in fire and rescue equipment. Offered in a 23 gross hp rating, the engine incorporates an open-loop EFI system developed by Japan=E2=80= =99s Kokusan Denki Co.

The Vanguard small-block engine with recoil start has been specified by a global manufacturer of fire equipment for a portable generator set used in fire and rescue applications

I bet that will create quite some interest in the flying =C2=A0apparatus circles. If the EFI = is using a MAP sensor or mass flow meter, the EFI would be fully altitude-compensating to 3,000+ meters (10,000'). Unfortunately, I haven't been able to source a parts manual yet to check what components are used in the EFI system.
